What are MojoAuth and Auth.js?

MojoAuth logo
MojoAuth

MojoAuth is a tool that lets users log into apps and websites without typing passwords. It offers several ways to verify who you are, such as sending a special link to your email, texting a code to your phone, or using your fingerprint or face scan.

The platform uses modern security standards called FIDO2 and WebAuthn. These make it nearly impossible for hackers to steal login information. MojoAuth also lets users sign in with accounts they already have, like Google or Facebook.

There are three pricing plans available. The free plan works for smaller sites with up to 25,000 active users per month. Paid plans add more features and support bigger companies. All plans include strong security protections built in.

Auth.js

Auth.js is a complete authentication solution that works across different JavaScript frameworks. It provides everything needed to add secure login systems to websites and applications. You can let users sign in through their existing accounts on services like Google or GitHub, or you can use email-based magic links, or even traditional username and password combinations.

The library is runtime agnostic, meaning it adapts to work with Next.js, SvelteKit, Express, Qwik, and other frameworks. It handles session management, protects routes, and connects to databases when needed. Auth.js follows web standards and security best practices, making it both safe and reliable. Since it is open source, the code is publicly available for review and contributions from developers worldwide.
